For this case, the first thing we must do is define a variable.
We have then:
x: unknown number.
We now write the equation that models the problem:
[tex] 10x = 0.5
[/tex]
From here, we clear the value of x.
We have then:
[tex] x = \frac{0.5}{10}
x = 0.05
[/tex]
Completing the sentence we have:
0.5 is 10 times as much as 0.05
Answer:
0.5 is 10 times as much as 0.05
